Description
Technical field
The invention belongs to desinsection product technical fields, and in particular to a kind of insect aerosol and the preparation method and application thereof.
Background technique
Vectors pest damage people's life and health such as mosquito, fly, cockroach, the level of preventing and treating it have been included in urban civilization degree
Measurement index even measures the national safe and comfortable horizontal very important index of the people.Insect aerosol, which has, uses carrying side
Just, the advantages that storage stability is good is that household sanitation desinsection defends common product, and in China, annual sales amount is more than 10,000,000,000.
However, studying the molecule of efficient pesticides as regulation of the department of the Chinese government to hygienic insecticide safety is increasingly stringenter
Structure is more complicated, and the probability for developing excellent new pesticides is lower and lower, and the development time greatly prolongs, and exploitation funds are huge,
The application for greatly limiting insecticide, the defect that the insecticidal effect for being difficult to insecticide caused by overcoming drug resistance to generate weakens.
Currently, insect aerosol on the market passes through several effective components of compounding largely to improve insecticidal activity and delay
The generation of drug resistance, especially using the insect aerosol of aqua type as the hot spot of current research.The insect aerosol green of aqua type
Environmental protection meets the environmental protection concept of current energy-saving and emission-reduction, is the mainstream of insect aerosol development from now on.However, existing commercially available life
Produce water-base pesticide aerosols be water-in-oil type, this kind of product liquid phase when static can be divided into two layers, upper layer be propane, butane and
The enriched layer of insecticidal active ingredient, lower layer are water-in-oil emulsions, and therefore, this kind of product has the following problems when in use:
Since the chemical analysis of this kind of product is unevenly distributed, it must sufficiently be shaken up before；Medical fluid after part sprays is in cream
Shape liquid influences the using effect of product；Kerosene content in the water-base pesticide aerosols of water-in-oil type is higher, accounts for about total weight
10% or so, when use, can inevitably generate sharp aroma.
The Chinese patent application of 104137852 A of Publication No. CN disclose a kind of water base domestic insecticide aerosol and its
Preparation method, the insect aerosol are used as effective component, addition by plant insecticide and pyrethroid insecticides compounding
Surfactant, inhibition anti-corrosion additive, bleeding agent, solubilizer, complexing agent, wetting agent, defoaming agent, excipient and essence preparation and
Be in homogeneous phase transparent at, water base domestic insecticide aerosol content liquid obtained, do not have to shake up using preceding, to mosquito, fly, cockroach, ant,
Termite, mite, tick etc. have the characteristics that multi-functional (MIK) of preferable repellent action and lasting period length.
Although the prior art is made that various effort to the formula and production technology that improve water-based type insect aerosol,
But still there are many defects, it is fewer and fewer really to can enter market product for consumer use, therefore, it is necessary to provide one
The novel insect aerosol and preparation method thereof of kind, to meet the needs of market.
